Simplify completely 12 times x to the third power minus 4 times x to the 2nd power plus 8 times x all over negative 2 times x. (

jok3333 [9.3K]

So we want to simplify
$\frac{12 {x}^{3} - 4 {x }^{2} + 8x }{ - 2x}$
We split the numerators,

$= \frac{12 {x}^{?3} }{ - 2x} - \frac{4x {}^{2} }{ - 2x} + \frac{8x}{ - 2x}$
$= - 6 {x}^{2} + 2x - 4$
The correct answer is B.

Zara has forgotten her 4-digit PIN code. She knows the first digit is a prime number and the 4 digits make a number divisible by

vredina [299]

Answer:

2,500 different sets

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Let 4-digit PIN code be WXYZ

As first digit is a prime number

So, W = 1, 2, 3, 5, 7

n(W) = 5

X and Y are number from 0 - 9

So, n(X) = 10 & n(Y) = 10

Z makes the whole number divisible by 2.

So, Z must even number

So, Z = 0,2,4,6,8 or n(Z) = 5

We can calculate the number of different sets by using following formula,

n(W) × n(X) × n(Y) × n(Z)

By putting the value, we get

5 × 10 × 10 × 5 = 2,500

You work for a dress maker and your boss sends you to the fabric store to buy blue fabric she tells you to buy the best deal wha

PSYCHO15rus [73]

Given <span>20 yards for $30.00, unit rate = $30 / 20 yards = $1.5 per yard

Given 40 yards for $45.00, unit rate = $45 / 40 yards = $1.13 per yard

Given 50 yards for $70.00, unit rate = $70 / 50 yards = $1.4 per yard

Given 65 yards for $85.00, unit rate = $85 / 65 yards = $1.31 per yard

The best deal is the cheapest rate which is 40 yard for $45.00

If we imagine it in our head, we can see that the width (base) is 2 and the height is 9
the area is 1/2bh or 1/2*2=9 square units
it is rotated around x axis
meaning we have a sideways cone that is 2 hight and radius is 9
Vcone=1/3(hpir^2)
h=2
r=9
V=(1/3)(2)(3.141592)(9^2)
V=(2/3)(3.141592)(81)
V=(54)(3.141592)
V=169.6459
round
V=169.6 cubic units

base is 2 units
height is 9 units
area is 9 square units
it's a cone (sideways)
it has a volume of 169.6 cubic units
